In the classic tradition of Sun Tzu's The Art of War, here for the first time in English is the timeless wisdom of China's greatest emperor Tang Taizong (598-649 AD), which is still being studied more than 1300 years later as an invaluable guide to leading and managing.

Tang Taizong is arguably the greatest Emperor in Chinese history. In Asia, many historians rank him with such rulers as Augustus, Genghis Khan, and Napoleon. When he founded the Tang dynasty, Taizong was only twenty-eight years old, and his chief accomplishments were on the battlefield, where he personally slew 1,000 of the enemy. Ultimately, he would defeat the descendants of Attila the Hun, open up the Silk Road trading route, create a golden age of prosperity and cosmopolitan culture, preside over a society in which women enjoyed higher status, and allow Christianity and Islam into China for the first time as well as introduce Buddhism into Tibet. His dynasty would last 300 years.

Here, author Chinghua Tang presents conversations between Taizong and his gifted advisers that reveal core aspects of leadership, among them: how to appraise oneself and assess others, how to enhance organizational effectiveness, how to compete with rivals, how to grow power and influence without losing the respect of others, how to learn from the rise and fall of predecessors, and how to craft one's legacy.

An indispensable guide that is as relevant for a middle-manager, military commander, or athletic coach as for a school principal, political leader, or over-stressed parent, The Ruler's Guide doesn't just reveal the insights that have kept Taizong's legacy alive, it spells out how that wisdom is a match for today's fast-paced, ever changing world.
